Question

I want to select more image files at a one time and upload as 1,2,3,4,… Like:

<form action="upload_file.php" method="post" enctype="multipart/form-data">
    <input type="file" name="imgs[]" id="imgs" multiple/> 
    <input type="submit" name="submit" value="Submit" />
</form>

PHP code:

<?php

if (file_exists("upload/" . $_FILES["imgs"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";

      }
    else
      {

//I think loop goes here 
===================
      move_uploaded_file($_FILES["file"]["tmp_name"],
      "upload/" . $_FILES["file"]["name"]);
      echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
===================

      }
?>

==================================================================

This is works…

<form action="upload_file.php" method="post" enctype="multipart/form-data">
    <input type="file" name="uploads[]" multiple>
    <input type="submit" name="submit" value="Submit" />
</form>

PHP

<?php
$count=1;
foreach ($_FILES['uploads']['tmp_name'] as $file) {
  echo '<li>' . $file . '</li>';

  copy($file, "uploads/" . $count.".jpg");
      echo "Stored in: " . "uploads/" . $count.".jpg";
    $count++;
}
?>

this is works….

Answer 1

PHP build the $_FILES array in a strange (but consistent) way when you have multiple upload. Try creating this form with three file inputs:

<form action="upload_file.php" method="post" enctype="multipart/form-data">
    <input type="file" name="imgs[]" id="imgs" multiple /> 
    <input type="submit" name="submit" value="Submit" />
</form>

Then in the PHP code that receive your form, place only:

<?php print_r($_FILES); ?>

So you can see the $_FILES array structure. At this point all will be clear to you, and you will get yourself how to loop on it to save all uploaded images. Good luck 😉
